Title: Method and device for numerical control
IPC: G05B19/23
Filed: 1961-09-25
Abstract: 967, 999. Numerical control systems. SVENSKA AEROPLAN A. B. Sept. 25, 1961 [Sept. 29,1960] No. 34266/61. Heading G3N. In a numerically controlled milling machine the command signal is recorded and compared with incremental pulses generated by the worktable slide decade by decade, the significance of an incremental pulse being appropriately reduced at each stage. The machine has four controlled movement axes, all identical, and consisting of a motor e.g. 77 and a pulse generater e.g. 78 which emits one pulse for every one hundredth of a millimetre movement of the work-table. One axis only is controlled at a time. The first binary coded numeral read from the tape 1 determines the axis in use and the direction of the movement; the signal being routed by a distributer 5 to set both a selector 33 for energizing the required motor via an unspecified controller 48, and to set a selector 29 for connecting the appropriate pulse generator to a decade counter 94, 95, 96, 97. The second and third coded numerals on the tape indicate tool spindle speed and tool feed rate and these are routed by the distributer 5 to selectors 49 and 63 respectively to affect the controller 48 in an unspecified manner. The fourth, and subsequent coded numerals until the final'stop' indicate the orders of magnitude of the displacement command signal and are all routed by distributer 5 to a selector 64 connected to the decade counter 94, 95, 96, 97. If for example, the first of these codes indicates that the units in use are decimetres, then the selector 64 connects an amplifier 4 to the final output of the decade counter so that one pulse is provided for each decimetre of work-table movement, i.e. the pulse train from 78 is divided by 10<SP>4</SP>. Each pulse supplied to the amplifier 4 causes the tape 1 to be advanced one step. The tape is left blank for as many steps as there are decimetres of work-table movement, and then the next order of magnitude code, e.g. centimetres, is recorded. The selector 64 is moved to the appropriate level of the decade counter and the process continues by stages down to the smallest increment available, at the end of which, the amplifier 4 is stated to stop the work-table motor 77. It is also stated that the feed speed is reduced for the smaller measurement units. In a modification, Fig. 8, (not shown) a separate counter is used to store the incremental command pulses in accordance with a recorded signal instead of using the tape reader as the counter by stepping off the blank steps. In a further modification, Fig. 12, (not shown), the pulse generator 78 is a photo-electric arrangement in which concentric rings on a disc interrupt the light falling on co-operating photocells in the required ratios.

Abstract: 826,944. Shutters for photographic stereoscopic cameras. GAUTHIER G.m.b.H., A. Dec. 2, 1955 [Dec. 3, 1954], No. 34596/55. Classes 98(1) and 98(2) In a shutter for a stereoscopic camera having a built-in delay action or flash synchronizing mechanism, the driving and release mechanism for the two shutter blade systems, a shutter speed escapement and means for setting the shutter speeds are mounted on a plate concentric with  one of the two objectives and a delayed action self-timer and/or a retard mechanism for synchronizing flash bulbs having a time lag are mounted on the second plate concentric with the other objective. One or more flash contact switches may be arranged to be actuated by the blade ring 6 of the second objective. As shown, the self-timer escapement mechanism 14 (Fig. 2), which is located beneath plate 15 in Fig. 1, is released by lug 6a, on blade ring 6, turning lever 31 to remove its arm 31a from the path of pin 32. Pallet wheel 25 is driven through train 21, 24, 20, 23, 19, 22, 18 and 17 by spring 29 and the escapement is uncoupled by disengaging pinion 20 and wheel 23 on turning lever 28 about the arbor of pallet wheel 25, the engagement being otherwise maintained by spring 27. Lug 6a on blade ring 6 is held by abutment 33a of lever 33 until the self timer mechanism has run down and it is then released by segment 17 moving levers 33 and 34 by means of pin 17b. A known shutter mechanism (the escapement of which is not shown) having a master member 9 and a release lever 12 is arranged on plate 2. Shutter driving spring 8 and spring 29 are tensioned by lever 36, pins 37 and 38 engaging arms 9c and 9d of master member 9 and pin 39 engaging lever 34. Arm 36c of lever 36 may be actuated either manually or by the film feed mechanism of the camera. Flash contact 44, 45 is closed by the co-action of pin 46 on blade ring 6 with arm 43b of bell-crank lever 43 and, when lug 47b on ring 47 is, as shown, adjusted to the depression V in detent spring 51, the contact is closed at the instant when the shutter aperture is uncovered. On turning ring 47 to the position X, pin 49 is carried along surface 50a of arm 50, turning the arm about its pivot to uncouple, by means of lug 28a on lever 28, self-timer mechanism 14. At the third position M pin 48 tilts mounting plate 42 so that pin 46 reaches arm 43b as lug 6a strikes abutment 33a on lever 33 thus providing a time lag for a flash bulb while the part 17, 18, 19, 22 and 33 of the self-timer mechanism runs down. The self-timer mechanism 14 may also be uncoupled by lever 52 on plate 2 which may be actuated by the shutter setting ring when this is set to " B ".

Title: Process for manufacturing high quality lubricating oils
IPC: C10G50/02
Filed: 1947-12-30
Abstract: Lubricating oils are prepared by alkylating alkylatable aromatic hydrocarbons in a first stage with normally gaseous olefin or dichlorethane in a reactor to form partially alkylated products, and thereafter feeding normally liquid olefins obtained by cracking paraffins into the reactor in a second stage, maintaining alkylation conditions whereby further alkylation with the liquid olefins or their polymers which are formed is effected, aluminium chloride being used as catalyst in both stages, and a fraction of the desired boiling range recovered from the product. The aromatic hydrocarbon may be benzene or crude benzol, and the reaction temperature 0-130 DEG  C.  In examples, benzol containing AlCl3 is reacted first with dichlorethane or gases obtained by cracking paraffin wax in the vapour phase, and then with a distillate boiling below 280 DEG  C. from the cracking of paraffin wax.  The Specification as open to inspection under Sect. 91 comprises the alkylation-polymerization of olefins such as petrol, white spirit or gas oil, for example those obtained by Fischer-Tropsch synthesis in the presence of aromatic hydrocarbons which are added either at the beginning or during the reaction.  Dichlorethane may be added prior to the said olefins or gases from the cracking of paraffin added before or after.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to swinging bridging members for use in mine cages and other moving structures
Inventor: CASE ALAN CLOUGH
IPC: B66B17/18
Filed: 1958-10-31
Abstract: 883,320. Bridging devices for feeding cars to mine cages and the like. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Oct. 29, 1959 [Oct. 31, 1958], No. 35032/58. Class 78 (4). The correct positioning of a swinging platform 14 between, for example, a mine cage and its landing, is proved by a toe 20 which is moved against a bias by engagement with the landing to control a power supply device, for example for decking equipment. In the form illustrated, the toe 20 has a slot 24 taking over a pin 12 on the swinging platform 14 so that when the platform is swung downwardly the outer end of the toe 20 engages an abutment 22 on the landing so that the toe 20 is turned about its heel 27 to raise a link 25 controlling the supply to the decking equipment. The toe 20 is shrouded by a depending portion 17 of a member 11 pivoted to the pin 12 and biased by its heel 15 to the position shown, this ensures that the toe 20 is operated only if it is correctly aligned with the abutment 22. To facilitate this alignment the floor of the landing may slope downwardly from both sides towards the abutment 22. A device shown is duplicated on opposite sides of the platform 14, and each member 11 carries a track rail aligned with a rail in the cage. In an alternative construction the toe 20 is omitted and the member 11 has a slot fitting over the pin 12 and is moved to control the supply to the decking means. In a further alternative the toe 20 pivots on the pin 12 without any vertical sliding movement, and its heel 27 is omitted; in this form the toe 20 is so balanced that it normally swings anticlockwise from the position of Fig. 5 to an extent limited by engagement with the tail 15 of the member 11; its clockwise movement from this position when it engages the abutment 22 causes it to operate a lever pivoted either to the platform 14 or to the bank. The member 11 may have two depending portions 17, one on each side of the toe 20. The toe may be biased by springs, instead of by gravity.
